What does it mean when a guy says, " I hope you won't be disappointed?" upon first meeting?

So, I met this guy; We don't know how each other looks; Nor, have we exchanged pictures. This Saturday we're meeting at a public place in my town. Every time we talk on the phone he says, " I hope you don't be disappointed." It's like I don't care how he looks; Nor is it important to me right now. How can I get him to see that his looks are at my standard because I realize that no one is perfect or can ever sum up to my dream man. The guy has what I'm looking for when it comes to standards. I just hope I don't be disappointed.
